Single throttle body EFI intake

Isn’t the small block Chevy intake port spacing fairly close to SBM? As in, if you had a set of intake flanges for a SBM you might be able to adapt something in the first picture to fit it? Or maybe use an eddy air gap knock off for the base plate and intake flanges? Obviously still some fabrication required, might be easier than a completely fabricated sheet metal intake though. And if the modification wasn’t too severe you’d have a better ballpark on intake flow.
